T0 aZZ w/wmz't mag/conceray v Be it known that I, JAMi sWV. IVORY," a subject of the King of Great Britain, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Tobacco- Pipe, of which the'following is a specification,

My invention consists of a "tobacco pipe having in its stem and bowl communicat i ing passages, one o'f'whi ch'is' open to the exterior ofsaid stem, and the otherl passage is open to the tob acc'oreceiving hamber et the bowl at the base 'therof, and a pin-like device which is adapted to occupy said, pa sj'.'

sages andc losethe's'ame to the exterior ;of

the stem, and provide a vent around said' pin-like device intermediate of the b'jowl and stem whereby smoke may be'drawii fromthe bowl around said device into the bore ot the stennineans being also provided for I holding'said pin suficiently tight in 'posi-' tion and permitting convenient, removal v i ,use'the smoke is drawn from the bowl into the vent '5' around thelfp'o'int portion of the ,clos'ur'e pin 8 'andffrom said vent directed intothe bore 7' of'the stem whereby. it my reach the mouthljof thesmoker;

therefrom.

The invention is sati factoril illustrated injthe accompanying drawing, butfthe-im portant instrumentalities thereof may be varied, and soit 'is to be"' understood=thatf the 'inventionis' not limited .to the specific;

In the pipe is a passage 3 which extends partly through said stem from the exterior thereof and partly through the lower portion of the bowl as at 4 when it opens into the tobacco chamber Got the pipe, it be:

ing noticed that said passage and bore are confluent, and the wall of said passage is cylindrical.

I i ll he n t'ifbed' also that the-tapering .stopper tightens' against the" outer portion lOofthe wallgof the passage 3-and "so re tain's its position by contact with the latter 'closure pin 8' therefor extend at, a[ rightangle Ito the; vertical PZILX'i'S ,of the bowl, f' In it will be; seenthat wheev the i i eflji a; 1

the chamber or th 'bowl' and the adjacent portions of the bore off-the stem may lOQ c removed therefrom through said passages outsidelof the pipe, thusjcle'aning the parts may be employed, .difieren't" from those [of-the pipe i -que tion after whichl t h clo surep;1n maybe restored tol' 'its poslt-ion a saees 3. i- 3144. w e the P pe is in the again; in condition for smoking.) a

The closure grasped/s0 as to. conveniently -manipu1ate the same for its introduction into 'the'passage 3 and removal therefrom.

In Fig; 4 I show forms of closure pins 12, and the other one having in it nearits air therethrough from the bowl into the stem. 1

Itwill be seen that in order to'have the andl'so nicotineand depositsat the-base of I ,isma'deofsuch lengthj that the"widerendthere'of projects beyond the surface of the underside ofthe stem form'- ing the handle 9 by whichsaid pin maybe 5 one having-near its pointthe reduced neck 75' ig ,3saidf passages nd i extend 7 q yt dax'is;

circumference of the pin as shown in Figs.

1 and 3, whereby both air and smoke may be forced out of the passage by breathing into the stem',ythus preventing the smoke from lodging and condensing in the passage.

As the tapered. end of the closure'pin terminates about the chamber 6 of the bowl of the pipe and centrally crosses 'thebore of the stem, the tobacco is: prevented from being drawn into said bore and further hinders thev burnin tobacco from bein disturbed b r breathing into the stem as so often s done while smokin to clear the oassa e. Said 1 p o v to pin also allows theexcess of smoke and air to distribute the pressure onthe tobacco in the bowl. To further assist this a small vent 11 is formed at a su table place in the bowl from the chamber 6 to the outer wall of the bowl so that a scarcely perceptible issueof smoke is apparent whenthe smoker breathes into the stem.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is Y 7 1. A tobaccojpipe having in the lower portion of its stem" and the base portion of its bowl communicating passages "which are open respectively to the tobacco chamber of the bowl and the exterior surface of the stem, and a tapering pin which is adapted to occupy said passages and form a closure for thelatter from the exterior of the stem, the portion of the passage adjacent to the bowl forming around the adjacent portion of the pin a vent by which smoke may be drawn from the bowl into the stem.

2. A tobacco pipe composed of a bowl and stem and havingiin the latter a passage which bisects the bore of the bowl, and a passage in s the base, of the bowl continuous of that in said stem, the first named passage being adapted to be open at the exterior of the stem, and the other namedpassage being open to the interior. of the tobacco chamber of the bowl, and a closure pin adapted to occupy said passage, and to be removably held therein, the end of the pin adjacent to the bowl being of less diameter than the passage that it occupies forming around said end a vent which provides a communication for the draft of the smoke from said chamber into the bore of the stem. V 3. A tobacco pipe having in the lower portion of its stem and the base portion of its bowl communicating passages 'which are open respectively to the tobacco chamber of the bowl and the exterior surface of the stem, and a tapering pin which is adapted to occupy said passages and form a closu'reforv thelatter from the exterior of the stem, the 1 portion of 'the passage adjacent to the bowl formingaround the adjacent portion of the pin a vent by which smoke may be drawnv from the bowl into the stem, said closure pin being removably held in the passage in the stem.

4. A tobacco pipe having in the lower por tion of its stem and the base portion of its] bowl communicating passages which are open respectively to the tobacco chamber of the bowl and the exterior surface of the stem, and a tapering pin which is adapted to occupy said'passa'ges and form a closureforthe latter from the, exterior of the stem, the portion of the passage adjacent to the bowl forming around the adjacent portion of the pin a vent by which smoke may be drawn from the bowl into thestem, said closure pin being removably held in the passage in the stem; and having an extension exterior of the stem forming a handle for locating the pin in position and removing it therefrom.

5; A tobacco pipe having in its stem and bowl a passage leading from the exterior of the stem to the chamberofthe bowl, and a tapering pin which is adapted to occupy said passage and provided in its peripherywith a vent for the purpose set forth.
